The Lake County Astronomical Society The pinkish-red color of nebulae, such as M42 in Orion or the Lagoon Nebula in Sagittarius, is really a combination of four different bright spectral lines of hydrogen gas. A hydrogen atom has a single proton at its center and a single electron in its outer region.

What causes the blue-green color of Uranus? The amount of helium in its atmosphere. Uranus's atmosphere is made mostly of methane, which reflects bluish-green light. The absorption of red light by methane crystals in the upper atmosphere of Uranus gives it its blue/green appearance.

Nebula Through supernova explosion: Some nebulae form by way of supernova explosions, caused by the collapse of massive, short-lived stars. The materials thrown off from the gigantic explosion are known as supernova remnants. Example: Crab Nebula. Through shedding off the outer layers of a low mass star: Other nebulae form as planetary nebulae. This is the final stage of a low-mass star's life, like our Sun. Such stars evolve into red giants and then blow off their outer layers of gas. These stars do not have enough mass to go supernova. Example: Ring Nebula.

Nebulae Dark Nebula-A dark nebula is a cloud of dust that blocks the light from objects behind it. They are very similar to reflection nebulae in composition and look different primarily because of the placement of the light source. fine example of an emission nebula is the Orion Nebula (M42). Reflection Nebula-A reflection nebula differs from an emission nebula in does not emit radiation of its own. It is a cloud of dust and gas that reflects the light energy from a nearby star or group of stars.

What is a nebula? how does it from a protostar? when does it become a star?? A nebula (Latin for cloud; pl. nebulae, nebulae, nebulæ or) nebulas is an interstellar cloud of, dust, hydrogen helium and other ionized. Gases, originally nebula was a name for any diffuse astronomical, object including galaxies beyond The Milky. wayxamples of these types of nebulae are the Rosette Nebula and the Pelican Nebula. The size of these nebulae, known as HII regions, varies depending on the size of the original cloud of gas. New stars are formed in the nebulae. The formed stars are sometimes known as a young, loose cluster.

- Recent images from the Cassini spacecraft now orbiting Saturn confirm that different rings have slightly different colors. The above image shows their sometimes-subtle differences in brightness and color. The rings reflect sunlight and so, even if they were perfectly reflecting, would appear the color of the Sun.

- As the name suggests reflection nebulas do not emit their own light, they reflect light from a nearby star. The energy emitted by the nearby star or stars is not sufficient to ionize the surrounding gas, so we don’t get the range of colors emitted by other nebulae.

- 1 The different colors produced by the Ring Nebula are the result of temperature differences, the hot inner gas is blue whereas the cooler outer gas is red.  The Ring Nebula is around 1 light year across and is expanding at a rate of 1.5 million kilometers per day.

The Milky Way Is a Snowy White, Astronomers Say They then took an average of those galaxies that most closely matched the Milky Way and determined a precise measurement of the galaxy’s color. Based on their findings, it appears the rate of star formation in the Milky Way is declining over time and the galaxy is in transition.

Planetary nebulae Planetary nebulae are astronomical objects made up primarily of gaseous materials. They are extended in size and fuzzy in appearance, and generally show some degree of symmetry. The nebula is illuminated by a central star, which sometimes is too faint to be seen.

Color Genetics in Quakers Simplified This is a similar effect as the Tyndall effect that makes the sky appear blue. So the green in Quakers is a combination of the yellow pigments (commonly called psittacins) and the blue structural color. The greys of the chest and dark color of the flight feathers and tail are produced by the grey or brown melanins.

Star Colors and Luminosities: The H-R Diagram Emission nebulae are usually red, because hydrogen, the most common gas in the universe, most commonly emits red light. Reflection nebulae are clouds of dust that simply reflect the light of a nearby star or stars. Reflection nebulae are usually blue, because blue light scatters more easily.n some nebulae, stars form out of large clouds of gas and dust; once some stars have formed inside the cloud, their light illuminates the cloud, making it visible to us. These star formation regions are sites of emission and reflection nebulae, like the famous Orion Nebula shown in the picture on the right.

- The Eagle Nebula is a diffuse emission nebula. A nebula is a region of interstellar gas and dust. Emission nebulae are clouds of ionized gas.The ionization comes from an extr … emely hot star that sends high-energy photons to the nebula. These nebulae usually appear reddish.eflection nebula are clouds of dust which are simply reflecting the light of a nearby star or stars. Such as the Witch Head Nebula. Emission nebula is a cloud of ionized gas (plasma) emitting light of various colors.

What Color is Saturn? Even through a small telescope, Saturn takes on a beautiful pale yellow with hints of orange. With a more powerful telescope, like Hubble, or images captured by NASA’s Cassini spacecraft, you can see subtle cloud layers, swirling storms mixing orange and white together.

Why Do Butterflies Have Such Vibrant Colors and Patterns? When you see blue, purple, or white on a butterfly, that's a structural color, while orange, yellow, and black are pigment, Prudic says. The nanostructure of the chitin, or wing scale, Prudic says, affects what light is reflected and how it's reflected..

- The size, shape and characteristics of nebulae may vary significantly because some are star nurseries and others are the remains of dead stars. Keep reading to learn more about dark nebulae, emission nebulae, reflection nebulae and planetary nebulae. Dark nebulae are found in areas that have no nearby stars.

- Uranus. The greenish color of it atmosphere is due to methane and This view of Uranus was acquired by Voyager 2 on January 10, 1986. The blue-green appearance of its atmosphere results from methane and high-altitude photochemical smog.he atmosphere of Uranus is composed of 83% hydrogen, 15% helium, 2% methane and small amounts of acetylene and other hydrocarbons. Methane in the upper atmosphere absorbs red light, giving Uranus its blue-green color.

- The Horsehead Nebula, one of the most famous dark nebulae, is located in the constellation Orion. 1  Emission nebulae are huge bright gas clouds with irregular shapes and dimensions that span many light years across. 2  Reflection nebulae are usually faint and shine with the reflected light of the stars within them. They are the remains from the former dense cloud of an emission nebula. Once stars are born inside an emissions nebula, they consume large amounts of the nebula's dust and gas, and the remains continue to shine with a faint reflected bluish light. An example is Pleiades in the Taurus constellation.

The Colour of Stars Most appear white but a few stars such as Antares and Betelgeuse have an orange or reddish hue to them. Others such as Rigel suggest a bluer colour. The colours of stars, however, are not obvious in most stars for several reasons discussed below. Colour is nonetheless an important and useful property of stars.

Star Colors and Luminosities: The H-R Diagram Eventually, all the helium in the core of the star is used up. At this point, what happens next depends on the mass of the star. The heaviest stars, over six to eight times as massive as our sun, have enough pressure in their cores to start fusing carbon.n some nebulae, stars form out of large clouds of gas and dust; once some stars have formed inside the cloud, their light illuminates the cloud, making it visible to us. These star formation regions are sites of emission and reflection nebulae, like the famous Orion Nebula shown in the picture on the right.

- The Aurora Borealis is most often seen in a striking green color, but it also occasionally shows off its many colors ranging from red to pink, blue to purple, dark to light.The reason that the aurora is seen in so many colors is that our atmosphere is made up of many different compounds like Oxygen and Nitrogen.ifferent atoms give off different colors of the spectrum when they are excited. A familiar example is the Neon lights that we see on many business signs in our modern world. The Neon lights contain the gas Neon. These lights have electricity run through them to excite the Neon gas.
